The Homogeneous Charge Compression Ignition (HCCI) combustionconcept lacks direct ignition timing control, instead the autoignition depends on the operating condition. Since auto ignition of ahomogeneous mixture is very sensitive to operating conditions, a fastcombustion timing control is necessary for reliable operation. Hence,feedback is needed and the crank angle of 50% burnt (CA50) has provedt

The anatomy of 11 genera earlier included in the Usneaceae, i.e. Bryocaulon Karnef., Chondropsis NyI., Cornicularia Hoffm., Evernia Ach., Everniopsis Nyl., Himantormia Lamb, Letharia (Th. Fr.) Zahlbr., Lethariella (Mot.) Krog, Protousnea (Mot.) Krog, Pseudevernia Zopf and Usnea Adanson have been examined. Particular emphasis has been paid to the development of the apothecia and the formation of a

In order to plan for and implement research on the outcome of the technical aid prescription process, more knowledge about the documentation of the process is imperative. The overarching aim of this study was to survey documentation quality aspects in patient records in community-based OT, with a particular focus on the technical aid prescription process. An additional aim was to compare the quali

An alternative experimental outline to measure homodyne detected three-pulse photon-echo data is presented. The novel experimental approach allowing for online monitoring and correction of experimental timing and stability is discussed in detail using the paradigm system of Nile blue in alcohol solution. It is shown that excellent signal-to-noise ratios together with high reproducibility of the da

Logarithmic norms are often used to estimate stability and perturbation bounds in linear ODEs. Extensions to other classes of problems such as nonlinear dynamics, DAEs and PDEs require careful modifications of the logarithmic norm. With a conceptual focus, we combine the extension to nonlinear ODEs [15] with that of matrix pencils [10] in order to treat nonlinear DAEs with a view to cover certain

OBJECTIVE: To ascertain whether the perinatal cerebral blood flow velocity differed between vaginally delivered appropriate for gestational age (vag. AGA) term babies, AGA babies delivered by Caesarean section (C.s. AGA), and small for gestational age (C.s. SGA) babies also delivered by Caesarean section. STUDY DESIGN: Forty-five babies were examined by Doppler ultrasound of the middle cerebral ar

Popular Abstract in Swedish Efter diskoteksbranden i Göteborg 1998, då 63 ungdomar dog och långt fler skadades, öppnades över 100 krisgrupper och krisjourer av stadsdelsförvaltningar, sjukhus och frivilligorganisationer. Avhandlingen bygger på intervjuer med 21 drabbade och 29 företrädare för olika krisgrupper. De drabbade fick av krisgrupperna praktisk hjälp och stöd t.ex. när de anhöriga skulle The aim of the dissertation is to study the organized professional process and the spontaneous integrating and unifying process after the discotheque fire in Gothenburg 1998, when 63 young people died. Over a hundred crisis groups and duty centres were opened for the affected people. These groups are composed of representatives of the social services, psychiatry, the churches and voluntary organiz

Abundant selachian remains have been recovered from a number of horizons through the Purbeck Group at Durlston Bay, Lulworth Cove and Stair Hole in southern England. The remains, primarily teeth, but additionally fin spines and dermal denticles, belong to selachians from two major groups, Hybodontoidea and Rhinobatoidei. The assemblage of hybodont sharks is quite diverse, comprising six species fr

Rate-distortion trellis source codes are developed for quantizing memoryless IID sources. The codes are generated by simple linear congruential recursions. The method generates codes at a variety of rates including fractional ones; reproducer sets can be large, a crucial advantage with certain sources. Axioms for good code construction are developed that are based on recursion properties, certain

beta-Phosphoglucomutase (beta-PGM), a 28 kDa monomer, catalyzes the reversible conversion of beta-D-glucose-1-phosphate to beta-D-glucose-6-phosphate in maltose metabolism in a variety of organisms. Sequence analysis of beta-PGM indicates that it is a member of the haloacid dehalogenase (HAD) enzyme superfamily, which evolved to cleave C-Cl, C-P and C-OP bonds in a variety of substrates. beta-PGM
